Could someone enlighten me pleaseThankyouPiston slap is the forged pistons moving in the bores while they are cold, once they expand when the engine has run for a while they should be quieter,Where is the tapping coming from? top end or bottom end? could be valve clearances, if you dont tension the cam drive gear it also makes the valve train noisier Quote
ktl Posted November 28, 2010 Posted November 28, 2010 is this a black quad you recently brought ? Quote
StarletMad Posted November 28, 2010 Author Posted November 28, 2010 does it go away once its warmed up????I wouldnt say goes away but definately becomes quieter....Yes ive recently got the car ktl. Quote

ktl Posted November 28, 2010 Posted November 28, 2010 i know the person you brought it from thats all, its tapped since he got the engine done. its def not piston slap cause i got the same forged bits and mine taps at start (minor) then goes once warm. but i noticed on that engine it taps and taps lol. its a head jobby either cams,or tappets me thinks.

StarletMad Posted November 28, 2010 Author Posted November 28, 2010 ktl can you tell me a little more about the bits then please as people keep questioning me and its doing my F***ing head in lol!i keep getting Have you got reciepts etc.... so annoying! Quote
shorty Posted November 29, 2010 Posted November 29, 2010 my forge is 10k old was always noisy, just rebuilt her and added some more goodies, still tappy. nature of the beast boys. if its alot from the top try tensioning the cam gear is a simple job but not for the unconfident as you have to drop the timing belt and whip ot the cams, again no biggy just makes noise it cant cause damage. piston slap is very normal for forged engines too but sounds more desiel engine than slappy. post a vid of it running makes it easier to help you out Quote
whiteglanzav Posted November 29, 2010 Posted November 29, 2010 ill just confirm it again lol forged engines do sound slightly worrying "tappy" when coldas it warms up the noise does become less noisy but will still be there a bit Quote
*sean_glanza_v* Posted November 29, 2010 Posted November 29, 2010 TGTT is your friend guys lolhttp://www.toyotagtturbo.com/forums/showth...attly-top-end-*am going to give this ago at the weekend and see if it helps! sorry for butting in on your post jonophilpott Quote
